Thereby, the movable shoji 4 is locked. At this time, the reverse rotation operation of the locking handle 51 is transmitted to the door rollers 10A, 10B and the airtight material gathering body 90 by the interlocking mechanism 6. Specifically, the reverse rotation operation of the locking handle 51 is transmitted to the first interlocking rod 74 via the vertical operating rod 72, and the first interlocking rod 74 moves from the position shown in FIG. ), the arcuate rod 73 rotates in the arc direction about the virtual rotation axis C while the shaft pins 7A are guided by the first guide groove 811 and the second guide groove 812. The interlocking rod 75 is extended and moved to the door butt side in the Y-axis direction, and by this movement, the lateral operating rod 60 is moved to the door butt side along the longitudinal direction of the lower frame 42. When the lateral operating rod 60 is moved to the door butt side, the second protrusions 65 move from the separated position shown in FIG. 7(B) toward the contact position shown in FIG. 7(A). When the contact top surface 67 abuts on the contact top surface 137, the door roller frame 13 is tilted in a direction in which the door surface frame 13 tilts outward while slidingly contacting the slope surface 138. The contact top surface 137 is located along the vertical direction. As a result, the door roller frame 13 and the wheel unit 14 are brought into the inclined state shown in FIG. 2, and the found surface of the lower frame 42 on the outdoor side is in close contact with the airtight material 221. The door roller 10B and the airtight material gathering body 90 are also in close contact with the airtight material 221 as described above.
In this way, the door rollers 10A, 10B and the airtight material gathering body 90 are operated in association with the unlocking of the locking device 5 and brought into close contact with the airtight material 221 to enhance the sealing property between the inside and the outside.

[Effects of this embodiment]
(1) In the above embodiment, when the contact surface 66 of the second protrusion 65 is pressed against the contact surface 136 of the first protrusion 135 by the sliding movement of the lateral operating rod 60, the door roller frame 13 moves the movable sliding door 4 Inclining so as to fall toward the airtight material 221 side in the prospective direction. Due to this tilting, the movable shoji 4 moves to the airtight material 221 side in its prospective direction, so that the movable shoji 4 is brought into close contact with the airtight material 221 of the window frame 2. Further, when the contact surface 66 of the second protrusion 65 is separated from the contact surface 136 of the first protrusion 135 due to the sliding movement of the lateral operating rod 60 in the opposite direction, the door roller frame 13 is moved by the weight of the movable shoji 4. In the upright state, the movable shoji 4 moves to the side opposite to the airtight member 221 side in the prospective direction, so that the movable shob 4 is separated from the airtight member 221. In this way, since the movable shoji 4 is brought into close contact with and separated from the airtight material 221, sliding resistance does not occur between the movable shoji 4 and the airtight material 221, and the opening/closing operability of the movable shoji 4 can be improved.
(2) The abutment surface 136 of the first protrusion 135 of the side piece 131 is arranged so that one end side in the sliding direction of the movable shoji 4 is located closer to the lateral operating rod 60 side in the prospective direction of the shoji than the other end side. Since the contact surfaces 66 and 136 are in contact with each other, the movable shoji 4 can be extruded and guided in the Z-axis direction toward the airtight member 221 side because the contact surfaces 66 and 136 contact each other.
(3) The contact top surface 67 of the second protrusion 65 extends in the vertical direction, and the contact top surface 137 of the first protrusion 135 inclines with respect to the vertical direction as shown in FIG. The angle is different from that of the contact top surface 67. For this reason, when the door roller frame 13 is inclined, the contact top surfaces 137 and 67 are in a state in which the contact top surfaces 137 and 67 are fitted together in the vertical direction. Since the contact area between the contact top surfaces 137 and 67 is wide in this way, the tilted state of the door frame 13 can be stabilized.
(4) When the protruding piece portion 143A protruding below the wheel 141 comes into contact with the vertical piece portion 251 of the lower frame 22 in the prospective direction of the movable shoji 4 in the inclined state of the door frame 13, the wheel 141 is pivotally supported. It is possible to suppress rattling in the specified direction, and more reliably maintain the airtight performance between the inside and outside.
(5) Since the locking device 5 is connected to the lateral operating rod 60 by the vertical operating rod 72 and the corner connecting device 71, the locking and unlocking operation of the locking device 5 causes the vertical operating rod 72 and the corner connecting device 71 to be connected. The lateral operating rod 60 can be moved in the sliding direction of the movable shoji 4.
(6) Since the lateral operating rod 60 interlocks the door rollers 10A and 10B respectively arranged on both end sides in the longitudinal direction of the lower frame 42, the door tips of the movable shoji 4 can be moved by tilting the door rollers 10A and 10B. It is possible to apply a force to bring the airtight material 221 of the window frame 2 into close contact with both the side and the tail side. For this reason, it is possible to prevent the airtightness from being deteriorated by bending the door tip side or the door tail side of the movable shoji 4 due to wind pressure.
(7) A link mechanism that transmits a force can be configured by the arcuate rod 73, the first interlocking rod 74, and the second interlocking rod 75. For example, when a corner connecting device that transmits a force while bending a flexible member is adopted, Compared with this, it is possible to transmit force with a small force. Further, since the first guide groove 811 and the second guide groove 812 are separated, the guide groove 81 is not formed in the portion where the first guide portion 82 and the second guide portion 83 are continuous, and accordingly, that portion is reduced accordingly. Can be slimmer.
